"For centuries, women have painted their lips red to enhance their appeal. The practice dates back as far as the Ancient Egyptians, who used red lipstick and rouge to enhance their attractiveness." said Dr. Geoff Beattie, who conducted the research.

"Our research suggests that red lips and perceived attractiveness are still ­inextricably linked, with red lipstick the most powerful attractor, and one that ­significantly increases visual fixation," added Dr. Beattie.
